“…Ion implantation is a novel surface modification technology to enhance the mechanical, chemical, and electronic properties of the surface of a material [11,[13][14][15]. In ion implantation, ion particles are accelerated by an electric field into the surface of the substrate material to change the composition of the surface (Figure 3).…”

The research on electromagnetic (EM) shielding has been advanced for various applications. Recently, researchers have been interested in nano-sized particles to modify electromagnetic properties of a base material. In this research, glass fiber-epoxy-nanoparticle composites (GFR nanocomposites) are fabricated using four types of nanoparticles, and their properties in electromagnetic shielding are compared. Carbon black (CB), multiwalled carbon nanotube (MWCNT), silver nanoflake (SNF), and silver nanopowder (SNP) are used as the added particles. For the visual observation of the nanocomposites, scanning electron microscope (SEM) and transmission electron microscope (TEM) are used. The characteristics of EM shielding of the composites are measured using HP8719ES S-parameter Vector Network Analyzer System for the frequency range between 8 and 12 GHz. Composites using MWCNT and CB show outstanding shielding effect of 17 and 43 dB, respectively, but silver nanoparticles do not show significant EM shielding. In addition, change of EM shielding characteristics by the ion implantation process is observed. After ion implantation, the EM shielding of the composites containing silver is increased in the frequency range.

“…In order to enhance the wear-resistant capability of aluminum and aluminum alloy, solid solution strengthening and thermal treatment strengthening can be adopted to improve the overall mechanical performance of the materials [3]. In addition, it is more environmental friendly and high efficient to modify the surface of aluminum and aluminum alloy matrix to obtain the hard surface deposition layer or form the compound layer and thus improve the wear resistance [4,5]. In all kinds of surface strengthening layers of aluminum and aluminum alloy, the nitride coatings (such as AlN and TiN) have attracted much attention [6,7].…”

In order to improve the wear resistance of the surface nitrided layer of 1060 aluminum matrix, the nitrogen containing thermal plasma Ti-assisted nitriding method was adopted to obtain the strengthening phases of AlN and TiN simultaneously. The influence of the nitriding technological parameter on Ti-assisted nitriding was studied through changing the nitrogen containing thermal plasma current (I = 100 to 160 A) and the flow ratio of the nitriding atmosphere (Ar/N2 = 8/2, 6/4, 4/6 and 2/8 L/min). The nitrided layer prepared under the Ti-assisted nitriding conditions was composed of AlN and Al solid solution, Al3Ti and TiN phases. The average microhardness of TiN dense distribution area was 1025 HV0.1, significantly higher than that of AlN dense distribution area (589 HV0.1). When the proportion of nitrogen in the plasma gas was 40% and the current was 120 A, the weight loss of the nitrided layer after wear was 3.4 mg, and its average friction coefficient was 0.214. Compared with those of aluminum matrix, the friction coefficient of the surface nitrided layer reduced by 33 %, and the wear resistance capacity increased by 4.5 times. Ti-assisted nitriding could obtain the AlN and TiN compound strengthening effect, so as to improve the wear resistance of the nitrided layer significantly.

“…Hence, it is necessary to improve the surface properties of aluminum and its alloy. Among the possible surface treatment techniques, nitrogen implantation has been proposed [3][4][5][6][7][8]. In this way, an aluminum nitride (AlN) layer is formed and previous studies have shown that the nanohardness and frictional properties of aluminum can be improved.…”

The effect of a AlN gradient interlayer on the surface mechanical properties was investigated by nano-indentation for the TiN film on N+-implanted Al substrate. The AlN interlayer, 80nm thick measured by Auger Electron Spectrometer (AES), was formed by high energy N+-implantation prior to magnetron sputtering the TiN film in our custom designed multifunctional ion implanter. The nanohardness of N+-implanted aluminum was 450HV at extremely small depth, but quickly decreased to a constant value (65HV). The hardness and Young’s modulus of the TiN film on two different substrates, one with and the other without N+-implantation, kept almost constant up to a small depth of 200nm, and then decreased to the values of the Al substrate with increasing indentation depth, but with a lower decreasing rate for the N+-implanted system. It was found from the load-displacement curves that the interfaces cracked when the indentation load was 38mN for the N+-implanted system, while 18mN for the unimplanted system. Therefore the N+- implantation improved the surface mechanical properties significantly.
